Example two

The second embodiment is optimized based on the first embodiment. The embodiments of the present invention are not detailed in the first embodiment, and are not described in detail herein.

Fig. 2 is a schematic structural diagram of an adjusting system according to a second embodiment of the present invention, in this embodiment, the actuator 230 includes two directional stepping motors 231, the number of the directional stepping motors 231 is two, and the axes of the two directional stepping motors 231 are respectively parallel to two legs of a right triangle formed by the distance measuring device 210.

The actuator 230 may be a mechanical device including two direction stepping motors 231.

The direction stepping motor 231 may be a motor having a direction adjusting function, and the stepping motor is a motor that converts an electric pulse signal into a corresponding angular displacement or linear displacement.

The number of the direction stepping motors 231 may be two, for example, the axial positions of the two direction stepping motors 231 may be perpendicular to each other, and the two direction stepping motors 231 perpendicular to each other in the axial direction may independently operate to adjust the charging plate separately, so as to adjust the charging plate in different directions. The direction stepping motor 231 may be provided on the base of the charging pad.

The axis of one of the direction stepping motors 231 may be parallel to one leg of a right triangle formed by the distance measuring device 210, and the direction stepping motor 231 may be configured to adjust distance information of the charging board in the direction of the direction stepping motor 231, so that the transmitting board and the receiving board are parallel.

Wherein, the controller 220 may adjust the number of steps by calculating an adjustment direction and a direction when it is determined that the difference is greater than or equal to the set threshold.

Fig. 3b is a schematic view of a direction according to a second embodiment of the present invention, as shown in fig. 3b, the horizontal direction is an x-axis direction, and the vertical direction is a y-axis direction.

The rectangular area in fig. 3b may be regarded as a charging pad, and the adjustment command of the x-axis direction stepping motor 231 is determined as an example, as shown in fig. 3b, first, the distance measuring device 210 may determine the distance information of two distance measuring devices 210 on the right-angle side corresponding to the x-axis direction stepping motor 231 from the target pad. The right-angle side corresponding to the direction stepping motor 231 may be a right-angle side perpendicular to the x-axis direction stepping motor, that is, a right-angle side in the y-axis direction in fig. 3a, and the right-angle side is a right-angle side in a right-angle triangle formed by the distance measuring device 210.

The controller 220 may determine a magnitude relationship between the difference of the determined distance information and a set threshold, and if the difference is greater than or equal to the set threshold, it may be determined that the transmitting board and the receiving board are not parallel, the adjustment instruction is to adjust the direction and the direction adjustment step number; the actuator 230 may acquire and execute the adjustment instruction, after the actuator 230 executes the adjustment instruction, the ranging device 110 may re-determine the distance information, the controller 120 may re-acquire the distance information re-determined by the ranging device 110, and the controller 120 may re-determine the adjustment instruction according to the re-acquired distance information. The above process is repeated until the difference between the distance information of the two distance measuring devices 210 is smaller than the set threshold, and the transmitting board and the receiving board are considered to be parallel, and the adjustment command is empty. When the adjustment command is empty, the actuator 230 may not perform any operation and make any adjustment.

When the adjustment instruction is null, the parallel adjustment in the y-axis direction of the transmitting plate is finished, and the parallel adjustment in the x-axis direction of the transmitting plate can be performed next, where the parallel adjustment process in the y-axis direction is consistent with the parallel adjustment process in the x-axis direction, and details are not repeated here.

The adjustment direction may be the direction in which the direction stepper motor 231 adjusts the charging plate, and may be determined by the difference in distance information from the target plate to two ranging devices 210 that are parallel to the two right-angle sides of the charging plate.

The adjustment direction can be realized through the central axis that direction step motor 231 rotated the charging panel and adjust the direction, exemplarily, explain with the adjustment direction of x axle direction as an example, first, confirm two distance measuring equipment on the right angle side of x axle direction on the charging panel apart from the distance information of target board, if two distance measuring equipment on the right angle side apart from the distance information of target board inequality, then can carry out the direction adjustment of the x axle of charging panel through the y axle central axis that direction step motor 231 rotated the charging panel. The principle of the adjustment direction of the y axis is the same as that of the x axis, and the detailed description is omitted here.

The number of direction adjustment steps may be the number of steps of rotation of the direction stepping motor 231, and the number of direction adjustment steps may be determined by the controller 220.

The set threshold may be a specific value, and the set threshold may be determined according to the accuracy of the actual ranging apparatus 210. If the accuracy of the ranging apparatus 210 can be determined to be in millimeters, the set threshold value may be a value in millimeters.

Further, the number of direction adjustment steps corresponding to each direction stepping motor 231 is determined based on the absolute value of the difference of the distance information of the two ranging apparatuses 210 on the leg perpendicular to the direction stepping motor 231 from the target board and adjustment position information, which is the product of the single step rotation angle of the direction stepping motor 231, the transmission ratio, and the distance of the leg from the rotational axis of the charging pad;

the adjustment direction of each direction stepping motor 231 is determined based on the distance information of the two distance measuring devices 210 on the right-angle side perpendicular to the direction stepping motor 231 from the target plate

The adjustment position information may be an adjusted distance of a single step of the direction stepping motor 231, the adjustment step number may be determined by the adjusted distance of the single step, and the adjustment step number may define the step number of the rotation of the direction stepping motor 231.

The adjustment position information may be calculated by multiplying a single step rotation angle of the direction stepping motor 231 by a transmission ratio and a distance of the square edge from a rotation axis of the charging pad, and the adjustment position information may be obtained by designing the transmission ratio as required to obtain desired adjustment position information.

The single-step rotation angle of the direction stepping motor 231 may be an angle by which the direction stepping motor 231 rotates after every rotation of one step.

The transmission ratio of the direction stepping motor 231 may be a transmission ratio of the direction stepping motor 231 to the charging pad, and the transmission ratio may be designed as required.

The distance of the right-angle edge from the axis of rotation of the charging plate may be the perpendicular distance from two right-angle edges on the distance measuring device 210 to the corresponding axis of the charging plate, and the two right-angle edges may be the right-angle edge in the x-axis direction and the right-angle edge in the y-axis direction. The distance of right angle limit distance charging panel axis of rotation can divide into the perpendicular distance of x axle direction right angle limit distance charging panel x axle direction central axis and the perpendicular distance of y axle direction right angle limit distance charging panel y axle direction central axis, and the distance of two directions can equal also can not be equal, and concrete numerical value does not do the injecing.

Further, the direction adjustment step number is a ratio of an absolute value of a difference of distance information of two ranging apparatuses 210 located on the same square side from the target board to twice the adjustment position information.

The number of direction adjustment steps can be determined by the ratio of the absolute value of the difference between the distance information of two distance measuring devices 210 on the same side of a right triangle formed by the distance measuring devices 210 from the target board to twice the adjustment position information.

The number of direction adjustment steps may include the number of adjustment steps of the x-axis direction stepping motor 231 and the number of adjustment steps of the y-axis direction stepping motor 231, and the number of adjustment steps in the two directions is calculated separately. If the same right-angle side is the right-angle side in the x-axis direction, the number of steps for direction adjustment can be the number of steps for adjustment of the stepping motor 231 in the x-axis direction; if the same square edge is a square edge in the y-axis direction, the number of steps for adjusting the direction may be the number of steps for adjusting the y-axis stepping motor 231.

According to the adjusting system provided by the embodiment of the invention, the actuator in the adjusting system comprises the directional stepping motor, and by utilizing the adjusting system, the parallel calibration of the transmitting plate and the receiving plate can be realized, so that the charging efficiency is improved.
